Topdon Artidiag 600s for serious stuff and Android app (TorquePro) on an old phone w/OBD2 Bluetooth adapter for quick look at standard stuff when running on my Sorento and GMC.
As far as my '94 Z28 I'm using 1990's DataMaster app for logging and a couple of other OLD OBD1 apps on an ancient windows laptop for reading/writing the tune. Still have an elm benchtop setup that allowed me to write different test tunes at my desk (I have two PCM's for the Z28 that I swap back and forth). The burning chips and writing to PCM days are long gone as cost of software and proprietary code from manufactures has killed the DIY tuning hobby.
